Dispensing device

ABSTRACT

The invention relates to a dispensing device for dispensing a preferably cosmetic liquid. Said dispensing device comprises an elastic or flexible pump section which can deform in a reversible manner in order to pump the liquid. The dispensing direction is preferably opposite to the direction of actuation. Several pump chambers are preferably arranged about a central outlet valve. Said dispensing device is preferably arranged on the base of an associated container. The outlet valve or the dispensing opening is preferably only opened during the first actuation. The liquid is distributed through a preferably hollow valve element, which also forms a nozzle.

The invention relates to a dispensing device as set forth in one of theindependent claims.

In the present invention, the term “dispensing device” is to beparticularly understood as a dosing pump or hand-operated pump for thedispensing of a preferably cosmetic liquid. However, it can also be anyother dispensing device such as a container, dispensing or spray head,dispenser or the like, particularly for a cosmetic liquid.

The term “cosmetic liquid” is to be understood, in a narrower sense, ascosmetics, hair spray, hair lacquer, a deodorant, a foam, particularlyshaving foam, a gel, a color spray, a sun protection or skin care agentor the like. Preferably, however, in a broader sense, other body careproducts, cleaning products or the like, and even suspensions andfluids, particularly those with gas phases, are included as well.Moreover, other liquids, for example air improvers and particularlytechnical liquids and fluids as well such as rust removers and the like,can as be used. Nonetheless, for the sake of simplicity and due to theemphasized use, there is often only mention of cosmetic liquid in thefollowing.

WO 2004/073871 A2 discloses a dispensing device with several pumpchambers. Each pump chamber is delimited by an elastically deformablepump part. These pump parts can be simultaneously deformed by a commonactuating element in order to dispense different liquids via a likewisecommon outlet valve simultaneously.

It is the object of the present invention to provide a dispensing devicewhich can be used universally, has a simple construction, a robustdesign, is simple to operate and/or, particularly, can be used overhead.

The abovementioned object is achieved by a dispensing device as setforth in one of the independent claims. Advantageous modifications arethe object of the subclaims.

One aspect of the present invention consists in that the dispensingdevice dispenses the conveyed liquid at least substantially opposite thedirection of actuation, particularly substantially in the middle andalong the middle or the longitudinal axis of the dispensing device. Thisallows for a simple and compact construction and universalapplicability.

Another aspect of the present invention which can also be implementedindependently consists in providing several pump chambers with elasticor flexible pump sections in order to be able to deliver the same liquidsimultaneously. Particularly, the pump chambers are connected orconnectable parallel to a container containing the liquid. This allowsfor a simple and robust construction. For example, the dispensing devicecan even be used if one of the pumps formed by the pump sections fails,for example due to an inlet or outlet valve that no longer opens.Moreover, the use of several pump sections or pumps allows for areduction of the volume of the individual pump chambers so that,particularly, a shorter total height is made possible.

As needed, the pump sections or the pumps can also be actuated one afterthe other, for example over an extended period of time, and/or they canmake another or continued delivery of the liquid possible upon continuedactuation of the dispensing device.

Another aspect of the present invention which can also be implementedindependently makes a provision that, in the ready-to-use state, thedispensing device is arranged on the bottom of a container and/or thedispensing direction is oriented substantially vertically downward. Thistoo allows for a very simple and robust construction. For example, asuction line into the container can be omitted. Moreover, the emptyingof the container and, particularly, an emptying of the container whichis as complete as possible is supported by gravitational force.Furthermore, this allows for very simple and intuitive operation, sincethe dispensing device or the pump part can be operated particularly bypressing down on the dispensing device and/or the container to dispensethe liquid.

Another aspect of the present invention which can be implementedindependently consists in that the dispensing device has at least onespring element arranged separately from the pump part in order tosupport or bring about the returning of the pump section. This allowsfor a simple and robust construction and an especially secure returningof the pump section.

Another aspect of the present invention which can also be implementedindependently consists in designing a valve element of the outlet valveof the dispensing device in a hollow fashion to dispense or conduct theliquid in the dispensing direction, particularly so that the valveelement forms a dispensing opening or dispensing nozzle of thedispensing device for the liquid. In particular, no other channel, head,dispensing nozzle or the like is then connected to the valve element.Rather, the dispensing of the liquid occurs directly from the outletvalve or its valve element. This allows for a particularly simple,robust and compact construction. In particular, only a few parts arenecessary, so that simple and cost-effective manufacture and assemblyare made possible.

Another aspect of the present invention which can be implementedindependently consists in that the dispensing device or its outlet valveor dispensing opening or nozzle is only opened upon initial operation.This allows for simple and uncomplicated handling and, particularly, anundesired premature running out of the liquid during storage or duringtransport can be prevented.

Another aspect of the present invention which can also be implementedindependently consists in providing the dispensing device with anopening means, so that when an associated container is changed out, itis opened by the opening means and a liquid connection to the inletvalve is established. This enables simple handling.

The proposed dispensing device can be used, for example, for airsprayers, air fresheners or other applications, for example fordispensing a medium from a flat glass, a cup, a dish, or the like. Thedispensing device can also in each case be used directly into a dish,cup or the like. Dispensing can occur optionally in liquid and/oratomized form. As needed, it is also possible to switch between the twoforms of dispensing.

Other advantages, features, characteristics and aspects of the presentinvention follow from the claims and the following description of apreferred embodiment on the basis of the drawing.

FIG. 1 shows a schematic section of a proposed dispensing device;

FIG. 2 shows an enlarged section from FIG. 1;

FIG. 3 shows another enlarged section from FIG. 1; and

FIG. 4 shows another enlarged section from FIG. 1; and

FIG. 5 shows a section of a modified embodiment of the dispensing devicecorresponding to FIG. 1.

In the not true-to-scale, merely schematic figures, the same referencesymbols are used for same or similar parts, with corresponding orcomparable characteristics and advantages being achieved even if arepeated description is omitted.

FIG. 1 shows a proposed dispensing device 1, particularly in the form ofa pump, for the dispensing of a preferably cosmetic liquid 2 in thesense named at the outset. The liquid 2 can be substantially moreviscous than water or optionally even pasty.

A container 3 for supplying liquid 2 is preferably associated with thedispensing device 1 to which the dispensing device 1 is preferablyattached or vice versa. In this manner, the container 3 or the like canbe changed out and/or the liquid 2 can be refilled. Alternatively, thedispensing device 1 can also form a reservoir for the liquid 2 or thecontainer 3 itself.

In the depicted example, the container 3 preferably has a collapsing bag3 a, particularly in a rigid container 3 b. The container 3 or thecontainer 3 b can preferably be detachably connected with the dispensingdevice 1 or vice versa. Particularly, the container 3 can be changed outor the dispensing device 1 can be used several times.

FIG. 5 shows a modified embodiment in a section corresponding to FIG. 1.Here, instead of the inner bag, a movable piston 3 c is arranged in thecontainer 3 b.

When removing liquid 2, the bag 3 a collapses (FIG. 1) or the piston 3 cmoves (FIG. 5). To this end, the container 3 or the container 3 bpreferably has a vent opening 3 d which can be covered, for example, bya label or the like (not shown) and, accordingly, is not visible to theuser. Alternatively or in addition, the vent opening 3 d can also beopenable by the user or automatically through the initial use of thedispensing device 1. Alternatively, the vent opening 3 d can also beintegrated into the dispensing device 1.

The dispensing device 1 is preferably embodied such that it is arrangedin the ready-to-use state at the bottom of the container 3 and/or thedispensing direction A runs substantially vertically downward. Inprinciple, however, the proposed dispensing device 1 can also be used inany orientation and/or with any dispensing direction A and/or alsotogether with other containers 3 or even without a container 3.

Especially preferably, the dispensing device 1 has an opening means,particularly in the form of a tapping element 3 e in order to open thecontainer 3, particularly its bag 3 a or a seal of the container 3 suchas a covering foil 3 f (FIG. 5), hence establishing a liquid and fluidconnection between the container 3 and the dispensing device 1, so thatthe liquid 2 can be removed. Especially preferably, very simple handlingis made possible by the opening means, since a putting on or connectingof the dispensing device 1 with the container 3 is sufficient to openand fluidly connect the container 3.

The dispensing device 1 can preferably be screwed with the container 3or container 3 b or connected in a locking manner. However, it is alsopossible for the dispensing device 1 to no longer be detachable from thecontainer 3 or container 3 b. In this case, the dispensing device 1 is,for example, adhered or welded thereto and/or engaged therewith.

In the following, the preferred construction of the dispensing device 1is explained particularly with reference to FIGS. 2 to 4. FIG. 2 shows,in an enlarged section of FIG. 1, the dispensing device 1 but withoutliquid 2 and without bag 3 a. FIG. 3 shows the dispensing device 1 inanother section. FIG. 4 shows the dispensing device 1 in yet anothersection.

The dispensing device 1 preferably has a first component 4, a secondcomponent 5 and/or at least one preferably elastically deformable pumppart 6 or an elastically deformable pump section 6 a—in the depictedexample, three pump sections 6 a. The preferred embodiment and functionof a pump section 6 a is primarily taken into account in the following.This preferably applies accordingly to the other pump sections 6 a.

The pump part 6 or second component 5 is connected or connectable withthe first component 4 preferably in an undetachable, liquid-tight and,particularly, gas-tight manner.

The first and/or second component 4, 5 is preferably designed to berigid and/or a single piece, and is particularly injection molded from asuitable, preferably food-safe plastic, particularly polyolefin, such asPP (polypropylene) or PE (polyethylene) or manufactured in anothermanner. The pump part 6 or the pump section 6 a, by contrast, isdesigned to be flexible or elastically deformable.

The second component 5 is preferably used to affix or hold the pump part6. Especially preferably, the pump part 6 is formed by the secondcomponent 5 or formed thereon or vice versa.

In the depicted example, the second component 5 is preferably injectionmolded onto the pump part 6 or connected undetachably and liquid-tightlytherewith in another manner. This makes simple manufacture possible, forexample by means of so-called “bi-injection,” i.e. particularly by meansof the injection molding of another material in the same injection moldin which a first material is formed. Particularly, a chemical and/ormechanical connection is thus made possible.

Alternatively or in addition, the second components can also beconnected or held together with the pump part 6 by means of an undercut,recess, through hole, overlap, or the like. Moreover, the pump part 6and the second component 5 can be embodied or manufactured as separatecomponents.

Especially preferably, an accommodating or pump chamber P for the liquid2 is formed between the first component 4 and the pump part 6 or pumpsection 6 a or bordered thereby at least in part.

Preferably, the pump section 6 a is designed to be at leastsubstantially dome-like or hemispherical or arched and/or the firstcomponent 4 has a preferably recessed area 4 a corresponding thereto orfacing same in order to form or delimit the pump chamber P. Especiallypreferably, the preferably single-piece pump part 6 or second component5 has several, particularly three such pump sections 6 a which formthree pump chambers P correspondingly. The first component 4 preferablyhas three recessed areas 4 a corresponding thereto which are indicatedin FIGS. 2 to 4 as being at least substantially dome-like.

In the depicted example, several or all pump chambers P are preferablyconnected to the same or a common liquid reservoir and serve to pump andconvey the same liquid 2.

The second component 5 is, as already mentioned, designed to berelatively rigid. By contrast, the pump part 6 or the pump parts 6—atleast the pump section 6 a or the pump sections 6 a—are designed to beelastically deformable or flexible in order to make possible the desireddeformation for reducing the size of the pump chamber P or the pumpchambers P for the pumping or conveying of the liquid 2. The differentmaterials, as already mentioned, are preferably connected with eachother such that a single component is finally formed. This facilitatesassembly considerably. In particular, it is then sufficient to connectthe second component 5 with the first component 4. This is preferablydone by means of ultrasound welding and/or in another suitable manner.

The dispensing device 1 preferably has an inlet valve 7 and an outletvalve 8. Preferably, the pump part 6 forms the inlet valve 7 and/oroutlet valve 8 together with the first component 4. However, the valves7, 8 can also be formed separately. The valves 7, 8 are preferablyembodied as self-closing one-way valves.

When the pump chamber P is filled with liquid 2, the volume of therespective pump chamber P can be reduced starting from the resting andinitial position shown in the figures through deformation of theassociated pump section 6 a, hence expelling and dispensing liquid 2from the pump chamber P. Particularly, to this end, an actuating element9, especially preferably a surface bearing the dispensing device 1(indicated in FIG. 2 for the same of example), a cap or the like (notshown) is moved in a direction of actuation B relative to the firstcomponent 4, particularly by pressing the dispensing device 1 or thecontainer 3 down in the direction N, hence deforming the pump section 6a at least in areas and reducing the size of the pump chamber P.

The outlet valve 8 or the nozzle 17 is preferably arranged at leastsubstantially in the middle of the dispensing device 1 and/or betweenthe pump parts 6 or the pump chambers P.

As mentioned earlier, an actuation of the dispensing device 1 or atleast of a pump section 6 a, especially preferably of several or allpump sections 6 a, occurs by pressing down on the dispensing device 1 orthe container 3.

However, it is also possible, for example, for a user (not shown) topress directly on the pump section 6 a or for another object to press oract thereon in order to dispense liquid 2.

Upon deformation of the pump section 6 a and reduction in the size ofthe pump chamber P, the liquid is dispensed or delivered via the outletvalve 8. Particularly, the opening of the outlet valve 8 occursautomatically, preferably as a result of the pressure of the liquidand/or—optionally additionally—as a result of a correspondingdeformation of the pump section 6 a upon actuation.

In the depicted example, the outlet valve 8 is preferably arrangedlaterally beside the pump sections 6 a, particularly in the middle.

The outlet valve 8 preferably has a valve element 10 which isparticularly designed to be a single piece with the pump part 6. In thedepicted example, the valve element 10 is preferably held by aconnecting section 11 and preferably connected with the pump part 6. Theconnecting section 11 surrounds the valve element preferably in anannular shape or in the form of a flange. The connecting section 11holds the valve element 10 preferably on an associated valve seat 12 ofthe outlet valve 8. In the depicted example, the valve seat 12 isparticularly embodied in an annular shape or as a conical ring.Especially preferably, the valve seat 12 is designed as the frontsurface of a recess 13 which is closed at the end and/or is formed bythe first component 4, particularly molded therein.

The opening of the outlet valve 8 occurs particularly through axialmovement of the valve element 10. This is particularly possible as aresult of the elastic deformation of the connecting section 11 or ofother variable areas.

The outlet valve 8 is preferably connected to the associated pumpchamber P, preferably in a parallel manner to all pump chambers P, via aconnection channel 14 and/or an annular channel 15 enclosing the valveseat 12 radially to the outside. Upon pumping or actuation of the pumppart 6 or the pump parts 6, liquid 2 located in the pump chambers P isput under pressure and leads, particularly, to a deformation of theconnecting section 11 which is such that the valve element 10 is liftedaxially off of the valve seat 12, i.e. the outlet valve 8 opens. Theliquid 2 can then flow into the recess 13, particularly radially.

Moreover, the dispensing device 1 preferably has a delivery channel 16and/or a nozzle 17. Especially preferably, the delivery channel 16and/or the nozzle 17 are formed by the valve element 10. In particular,the valve element 10 is hollow for this purpose and/or is provided witha corresponding through-channel, particularly one which runs axially orin the direction of movement or in the dispensing direction A. In placeof the preferably formed nozzle 17, a flat nozzle in the depictedexample, the dispensing device 1 or the outlet valve 8 or the valveelement 10 can also have only a dispensing opening formed, for example,by the delivery channel 16.

When the outlet valve 8 is open or the valve element 10 is lifted off ofthe valve seat 12, the liquid 2 flowing into the recess 13 isparticularly diverted and delivered through the valve element 10 orthrough the delivery channel 16, a dispensing opening formed therebyand/or the nozzle 17. In the depicted example, the outlet valve 8 orvalve element 10 therefore are used particularly for the directdispensing or delivery of the liquid 2. In particular, as a consequence,no other channels, diversions, delivery nozzles or the like connect tothe outlet valve 8 or its valve element 10, although this is alsopossible in principle and, accordingly, is not intended to be excluded.

Especially preferably, the dispensing device 1 or its outlet valve 8 orthe dispensing opening or nozzle 17 is only opened upon initialactuation. Particularly, the nozzle 17 is provided, for example, with avery thin wall 18 during manufacture in the area of its outlet openingor tip. Only upon initial actuation or dispensing of liquid does thepressure of the liquid cause the abovementioned thin wall 18 to rupture,hence opening the nozzle 17 or the liquid dispensing or the dispensingdevice 1. However, other constructive solutions for achieving thedesired effect are also possible here.

The dispensing direction A preferably runs at least opposite thedirection of actuation B and/or at least substantially parallel toand/or in the middle axis M of the dispensing device 1 and/or at leastsubstantially parallel to and/or in the longitudinal axis L of thecontainer 3 (cf. FIGS. 1 and 2).

After the dispensing of liquid and the respective drop in the liquidpressure in the pump chambers P or in the annular channel 15, the outletvalve 8 preferably closes again automatically, particularly as a resultof the restorative forces of the connecting section 11. However, otherconstructive solutions are also possible here. A return spring or thelike can also be used here as needed.

After the dispensing of liquid is completed—particularly after thepressing down of the container 3 or the dispensing device 1 has ended orafter the container 3 or the dispensing device 1 has been released—thereoccurs a preferably automatic return of the pump section 6 a or the pumpsections 6 a into the initial position shown in the figures, with newliquid 2 being taken up, preferably sucked, via the inlet valve 7 or theinlet valves 7 into the pump chamber P or the pump chambers P. Theopening of the inlet valves 7 during the return to the initial positionoccurs particularly as a result of the negative pressure prevalent thenin the pump chambers P.

According to a preferred aspect, the dispensing device 1 has at leastone spring element 19 which is particularly arranged and embodiedseparately from the pump section 6 a or the pump sections 6 a and actsdirectly on the actuating element 9 in the return direction R—i.e.flexible in the axial direction or direction of actuation B—in order tosupport or bring about the return of the pump section 6 a or the pumpsections 6 a.

Preferably, the spring element 19 is designed to be arch- or bow-like.However, any other shape is possible here.

Preferably, the height or axial extension of the spring element 19corresponds substantially to that of the pump sections 6 a and/or thespring element 19 points in the same direction or in the axialdirection.

Especially preferably, the spring element 19 is arranged on thedispensing device 1, particularly on the second component 5 or pump part6, and is embodied as a single part therewith, preferably molded orinjected thereon.

Preferably, several spring elements 19 are provided which are preferablydistributed peripherally along the circumference of the covering device1 and/or arranged in a diametrically opposing manner which is such thatthe dispensing device 1 exhibits good stability even in the case of avery long and/or heavy container 3 or container 3 b.

Especially preferably, the spring elements 19 are arranged radiallyoutside and/or around the pump section 6 a or the pump sections 6 aand/or the outlet valve 8.

In the depicted example, the second component 5 has at least onepreferably bridge-like projection 20 which engages in a groove 21 in thefirst component 4 and is connected therewith—particularly by means ofultrasound welding—in a liquid-tight manner.

Especially preferably, the second component 5 has a raised area 22 onthe side opposite the projection 20 which facilitates the placement of atransmission element (not shown) for the introduction of ultrasound andhence a focusing of the ultrasound onto the desired area to beconnected. The liquid-tight connection formed extends, particularly,around the pump part 6 or the pump sections 6 a.

In the depicted example, a separate inlet valve 7 is preferablyallocated to each pump chamber P. Particularly, in this regard, a valveseat area 23 with a valve opening 24 toward the container 3 is formedfor accommodating liquid 2. Moreover, a valve flap 25 is preferablyarranged on the pump part 6 or separately on each, particularly embodiedin one piece with the pump part 6 or formed therefrom, and particularlypretensioned in the manner of a leaf spring or elastically against thevalve seat area 23 to cover or seal the valve opening 24 as indicated inFIG. 4 for a pump chamber P. The valve flap 25 therefore lies on theinside of the pump chamber P at the valve seat area 23.

Upon the return of the pump sections 6 a into the initial position shownin the figures, the outlet valve 8 is closed. Accordingly, negativepressure is formed in the pump chambers P, so that the valve flaps 25open toward the outside and thus release the valve openings 24, henceopening the inlet valves 7. In the preferred arrangement of thedispensing device 1 at the lower end of the container 3, thegravitational force is conducive to the filling of the pump chambers Pwith the liquid 2 upon return. Moreover, emptying can be achieved atleast to the greatest possible extent.

As needed, channels 26 can be additionally provided on the valve seatareas 23 on the outside in order to support an emptying of the container3 which is as complete as possible.

Individual features and aspects of the various embodiments can often becombined with each other as desired or used in other dispensing devicesor the like.
